The shelf life of polyester nonwoven fabrics is mainly affected by environmental conditions, material stability, and packaging methods.

Industry Background and Market Demand Electrical installations require materials that ensure safety, durability, and compliance with stringent fire safety regulations. Flame-retardant (FR) polyester fiber nonwoven fabrics have emerged as a critical component in electrical insulation, cable wrapping, and protective barriers due to their ability to resist ignition, slow flame spread, and minimize toxic smoke emissions.

Introduction The electrical insulation industry relies on materials that ensure safety, efficiency, and durability in high-voltage and high-temperature environments. Among the various options available, nonwoven fabrics have gained prominence due to their unique structural and functional advantages. This article explores the role of nonwoven fabrics in electrical insulation, examining their properties, manufacturing processes, key performance factors, and emerging trends in the field.

Improving the anti-aging properties of electrical nonwoven fabrics can be approached through material modification, process optimization, and the use of additives. Material modification includes selecting highly stable polyester fibers or blending them with other aging-resistant fibers. For example, adding aramid or glass fibers can improve the thermal stability and UV resistance of the nonwoven fabric. Furthermore, introducing aging-resistant groups through chemical grafting or surface treatment can also slow down the aging process.

Industry Background and Market Demand The demand for reliable electrical insulation materials continues to grow across industries such as power generation, automotive, aerospace, and consumer electronics. As electrical systems become more complex and operate under higher voltages, the need for durable, heat-resistant, and lightweight insulating materials has intensified.
